I've an interest in helping to develop a kernel testsuite for NetBSD.
I've spoken to Luke Mewburn about it and he thinks it's worth
discussing on this list, so here it is :-)
I've been giving thought to testing the kernel using a virtualisation
system like Xen. If we presuppose that NetBSD, being so portable, has
a minimum amount of machine dependent code, we can get a good
approximation for all NetBSD ports by testing NetBSD/xen on a Xen
system. This would involve modifying Xen so that the behaviour of the
underlying virtual hardware could be manipulated by a scriptable
interface.
Tests could be scripted such that a variety of hardware events could
be triggered and the kernel's response to these tested (eg. disk
errors, bus timeouts, etc).
Any comments? Is this worth pursuing?
Ben
